(WILEY-V C H VERLAG GMBH, 2007-04)We report on the analytical performance of glassy carbon (GCE) electrodes modified with a dispersion of multiwall carbon nanotubes (CNT) in chitosan (CHIT) for the quantification of DNA. The electroanalytical response of ...
-
(2011)This work reports the electrochemical response of the complex between dsDNA and PEI formed in solution and at the surface of glassy carbon electrodes (GCE) modified with a dispersion of multi-walled carbon nanotubes in ...
-
(ELSEVIER SCIENCE SA, 2003-01-16)The electrooxidation of primary alcohols with four to eight carbon atoms on black Pt electrodeposits on gold/quartz, and on commercial bright platinum/quartz electrodes in perchloric acid solution, was studied by cyclic ...
-
(ELSEVIER, 2006-11-11)The philicity indices, omega(N), and omega(+)(S), characterize a charge transfer process occurring at constant spin number, and the spin polarization for a process at constant number of electrons, respectively. These ...
-
(1987)The developmental processes related to odontogenesis are similar in all vertebrates and they occur during embryogenesis. The dental papilla can exercises directive morphogenetic role on epithelia of different phylogenetic ...

(Sociedad de Neurologia Psiquiatria y Neurocirugia, 2016)Guillain Barré syndrome is an acute polyradiculoneuropathy with different forms of presentation and is currently the leading cause of acute arreflexic paralysis in the world, its diagnosis is clinical and additional assesment ...
-
(ELSEVIER, 2006-02-09)Petrosal ganglion neurons are depolarized and fire action potentials in response to acetylcholine and nicotine. However, little is known about the subtype(s) of nicotinic acetylcholine receptors involved, although alpha 4 ...
-
(2011)Potassium channels (K+ channels) are members of one of the largest and most diverse families of membrane proteins, widely described from bacteria to humans. Their functions include voltage-membrane potential maintenance, ...

(1988)1. 1. In spontaneously beating preparations of sinus venosus of the frog Caudiverbera caudiverbera the electro-physiologic effects of verapamil on action potential parameters of both primary and transitional pacemaker cells ...
-
(1992)The electrical activity of single units located in the parvicellular part of the red nucleus (pRP) was recorded extracellularly in nitrous oxide anesthetized and C1-transected adult cats. In this area, neurons were found ...
-
(1977)In 40 unanaesthetized, curarized cats, the reciprocal electrophysiological relationship between the caudate nucleus and the Pul-LP complex was analyzed. With pulses I/sec applied to the pulvinar nucleus, evoked responses ...
-
(ELSEVIER SCIENCE BV, 2004-12)The organization and regulation of excitatory synapses in the mammalian CNS entails complex molecular and cellular processes. In the postsynaptic membrane, scaffolding proteins bring together glutamate receptors with ...
-
(Universidad de Chile, 2016)En la búsqueda de semiconductores poliméricos de fácil procesamiento para su aplicación en celdas solares orgánicas (CSO), esta tesis abordó la electropolimerización de derivados de tienilvinileno en una serie de líquidos ...
-
(ACADEMIC PRESS INC ELSEVIER SCIENCE, 2006-07)The combination of accessible embryology and forward genetic techniques has made zebrafish a powerful model system for the study of vertebrate development. One limitation of genetic analysis is that the study of gene ...
-
(Elsevier Ltd, 1997)Electrochemical studies on 4-(nitrophenyl) substituted 1,4-dihydropyridines of pharmacological importance have allowed us to generate the one-electron reduction product, the nitro radical anion, ArNȮ- 2 , in aprotic media. ...
-
(PERGAMON-ELSEVIER SCIENCE LTD, 1997)The electro-reduction of nitrate ions in acid medium on Pt, Ir and on a 70:30 Pt, Ir alloy was studied by cyclic voltammetry. The alloy has a higher activity than the pure metals, which was interpreted as being due to ...
